Glass-filled PTFE compounds are the most universally used. It can be utilized at service temperatures from -268 °C to +260 °C in chemical service ranging from liquid oxygen to fuming nitric acid, in severe wear pads for railway cars, and for self-lubricating compressor rings for non-aluminum cylinders.

PTFE compound applications:

Bearings

Gaskets

V-rings/O-rings/Back-up rings

Hydraulic ring seals

Non-lubricated compressor rings

Valve seats and liners/swivel liners

Thrust washers

Lip seals

Standoff insulators

Feedthrough insulators

Pelletized compounds are produced in an environmentally friendly manner. They are easily processed in automatic molding equipment and are used primarily in automotive parts. Non-pelletized compounds are used in applications that demand the highest mechanical strength.
